6.7.2 Advanced magnetic flux vector control (Pr. 71, Pr. 80, Pr. 81, Pr. 89, Pr. 450,
Pr. 451, Pr. 453, Pr. 454, Pr. 569, Pr. 800)
Advanced magnetic flux vector control can be selected by setting the capacity, number and type
of motor to be used in Pr. 80 and Pr. 81.
●
What is advanced magnetic flux vector control?
The low speed torque can be improved by providing voltage compensation so that the motor
current which meets the load torque to flow. Output frequency compensation (slip compen-
sation) is made so that the motor actual speed approximates a speed command value.
Effective when load fluctuates drastically, etc.
Use Pr. 178 to Pr. 189 to assign the terminals used for the X18 and MC signal.
